June 12, 1934. M. B. SMITH Y GLIDER FRAME CONSTRUCTION Filed Sept. 14, 1935 Patented June 12, 1934 UNITED STATES PATENT OFFICE 1,962,917 GLIDER FRAME CONSTRUCTION Application September 14, 1933, Serial No. 689,454

8 Claims.

This invention relates to gliders of the type having a back and seat structure mounted for swinging movement between laterally spaced upright supporting frames, and an object is to produce a simple and efiicient frame construction according to which the parts can be readily assembled and disassembled without the use of bolts and nuts, thereby enabling the frame to be erected or knocked down more conveniently without the use of special tools and connecting devices.

For purposes of illustration, but not of limitation, an embodiment of the invention is shown on the accompanying drawing, in which:

Figure 1 is a perspective view of a glider frame having the back and seat structure in dotted lines;

Figure 2 is an enlarged perspective of a portion of one of the uprights with the cross or horizontal bar secured in place;

Figure 3 is a perspective View of an end portion of the horizontal connecting bar;

Figure 4 is an enlarged vertical sectional view on the line 44 of Figure 2; and

Figure 5 is a sectional view showing the manner in which the horizontal bar is connected to the end frames.

The illustrated embodiment of the invention comprises a glider frame having laterally spaced upright end frames 10 and 11, which are connected together by a horizontally disposed bar 12 which is disposed beneath the seat structure S, as indicated by the dotted lines on the drawing, and connected to the seat structure S is the usual back 13. The end frames 10 and 11 are of the same construction, and each comprises a foot member 13 to which are secured upwardly extending bars 14 and 15. Secured to the upper ends of the bars 14 and 15 is a horizontal bar 16 from the opposite ends of which may be connected hangers 17, which are suitably connected to the seat S. Disposed between the upright bars 14 and 15 at the lower ends thereof is a plate 18 which is secured by rivets 19 to the bars 14 and 15 and the foot piece 13. The upper end of the plate 18 is provided with an inwardly extending portion or ledge 20, which terminates in a downwardly and rearwardly inclined lip 21.

Secured to each end of the connecting bar 12 is a cross bar 22 which is riveted to the bar 12 intermediate its ends. To admit the connecting bar 12 an opening 23 is provided in the lip 21. It should be noted that the cross bar 22 is of angle iron or L-shaped in cross section having a horizontal portion 22 and a vertical portion 22*.

From the above description it will be apparent that the plate 18, the ledge 20 and lip 21, form a housing having opposed side walls (the plate 18 and lip 21) and an end wall (the ledge 20), into which housing the cross bar 22 is inserted in a manner hereinafter described so that the thrusts imparted by the connecting bar are effectively resisted.

In assembling the connecting bar and end frames, one or the other of these parts is tilted to enable the horizontal portion 22 of the cross bar 22 to be inserted beneath the lip 21 substantially as ind cated in Figure 5. Thereafter, by moving the part 22 inwardly into the socket provided by the lip 21 and the underside of the portion 20, the bar 12 may be swung downwardly so that the portion 22 of the cross bar 22 abuts against the plate 18 and the horizontal part 22 abuts against the inwardly extending portion 20 of the plate 18 so that as the parts are assembled, they assume the position as shown in Figure 4.

In order to retain the parts in assembled position an arm 24 is pivoted to each end portion of the connecting bar 12 at a point 25 spaced inwardly from the adjacent end of the bar. The arm 24 is provided with a bent end portion 26 having a hook 26 to engagea stud 2'7 on the foot bar 13. It will be noted that the bent end portion 26 engages the stud 27, but lateral motion and disengagement from the stud is prevented by a catch' 28, which is pivoted on a rivet 29 secured to the plate 18 and foot 13. In order to disassemble the parts, it is necessary that the catch 28 be swung upwardly to allow the arm 24 to be moved laterally, whereupon the parts may be disengaged by a reverse movement to that above described. When not in use the arm 24 may be swung upwardly against the underside of the connecting bar 12, which is of channel or U-shaped construction. 95

From the above description it is apparent that each of the upright frames 10 and 11 can be readily connected to or disconnected from the connecting bar 12 without the use of special tools or nuts and bolts. When the parts are in 100 assembled relation, an exceedingly sturdy frame is provided which, owing to the manner in which the connecting bar is joined to the upright end frames, obviates liability of squeaks and rattles during the use of the glider. The frame can be conveniently packed for shipment, and requires a minimum amount of space.

It is to be understood that numerous changes in details of construction and arrangement may be effected without departing from the spirit of the invention, as defined in the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. In a glider frame having a pair of laterally spaced uprights and a bar connecting said uprights, and means for connecting said bar to each of said uprights, each connecting means comprising a cross-bar connected between its ends to an end of said connecting bar, a housing in the adjacent upright to receive and retain said cross-bar, means for releasably holding said cross-bar in said housing.

2.
